프리즘 조명기구의 배광 메카니즘 모델링 및 최적화 기법의 적용 연구

The dome pendant prismatic luminaire is recently used in commercial and industrial high-bay applications where quality light levels and energy savings are imperative. In addition, it is satisfied with various luminous intensity distrbutions as well as aesthetic designs. Despite these advantages, up to now, most of luminaire designers have only concentrated their attention on the design matters without optical consideration. Even if they know accurate optic a calculation process, it's difficult to produce prismatic luminaire with luminous intensity distribution required in a space, because the design process is made by much trial and error. The process is also required much time to design. μ-GA is one of the improved form of GA, which has been used to find an opimum solution, to reduce iteration and computing resources by using small populations. Therefore, the purpose of this study is to introduce candlepower distribution model of dome pendant prism luminaire and to develope a design algorithm that is able to find an optimum design solution of the luminaire using μ-GA.

To control the lighting system automatically and save lighting energy, a lighting control system using the photosensor has been developed. Such a system has a function of controlling the luminous flux of the dimmed luminaires in a control space to maintain a design light level in response to available daylight. In this paper, the quantitative aspect of the system performance to an existing system and a developed system was evaluated and compared. In addition, cost-effectiveness of the system was analyzed to increase acceptability of such a system.

Quality of life is big issue recently Well-being, an idea of looking for healthy and wealthy body or mind in the basis of pro-health, pro-environment spirit, is going to be international trend instead of pursuing fortune and social position From this point of view, this paper investigated a meaning of light in the healthy environment and studied mental and physical effects of light sources, which ultimately affects luminous environment inn the residential areas This paper finally suggested well-coordinated lighting condition, derived from results of relationship between health and lighting, and demonstrated luminous environmental rendering simulation
인터넷 웹기반 RADIANCE 가시화 시스템의 개발 : I. 조명기구의 데이터베이스 구축

현재 빛환경의 평가도구로서 사용하고 있는 여러 조명 시뮬레이션 프로그램들은 대부분 국외에서 생산되고 있는 조명기구의 데이터를 바탕으로 하고 있다. 그렇게 때문에 국내 환경에 맞는 빛환경의 정확한 평가에는 한계를 가지고 있다. 본 연구의 진행은 사용자들의 편의성을 도모하기 위하여 실무에서 많이 활용되고 있는 조명기구를 선별하여 종류별로 분류하였다. 그리고 국내에서 생산되고 있는 조명기구의 데이터 수집을 바탕으로 RADIANCE 엔진을 이용하여 인터넷 웹기반 가시화 시스템 개발을 위한 조명기구의 데이터베이스를 구축하였다. In the present, most lighting simulation programs are based on luminaires data produced at overseas. Currently, it is difficult to use proper domestic luminaire database in most lighting simulation programs, because there are only oversea luminaire database available. Therefore, in this study, domestic luminaire database were developed and categorized, and applied to Internet Web-based RADIANCE rendering system. Luminaire database are constructed with 3D modeling, materials, and IES candlepower distribution data of each luminaire.
